The boy's mother, 24-year-old Jessica Linscott, is serving 2 ½ to 7 years in prison for failing to get her son medical help and coaching him to lie to a social worker. She has testified against Dow in Rockingham Superior Court, where the trial began June 10 and will resume Wednesday with further witnesses for the prosecution.

The couple was arrested at a Florida amusement park two weeks after leaving the toddler at a hospital with a severe brain injury and burns. The boy, now 5, lives with his grandmother.
